Even the tiniest of particles from human emissions can fuel powerful storms and influence weather and crops much more than previously thought, according to new research published January 26 in the journal Science. The study focuses on the power of manmade aerosol emissions to grow rain clouds and intensify storms. These particles come from urban and industrial air pollution, wildfires and other sources. While scientists have known that these particles play an important role in shaping weather and climate, the new study shows that even the smallest aerosol particles can have an outsize effect, creating more severe thunderstorms, which in ...
